pH Plus by EcoOne | Natural Hot Tub pH Increaser – Chlorine-Free, Phosphate-Free, 2 Lbs

EcoOne pH Plus is a natural granular powder designed to gently raise your hot tub’s pH. Made with sodium carbonate, it balances water without residues or strong odors. This 2 lb package offers a straightforward path to balanced water that feels comfortable as you soak.

The skin-friendly formula is 100% free of chlorine, phosphates, and other harsh chemicals, aiming for water that feels neutral on skin and eyes when you step into your spa. You may notice softer sensation and a calmer balance that supports routine spa care.

Crystal clear water and balanced alkalinity

Low alkalinity can lead to cloudy water and mineral buildup. EcoOne pH Plus helps support a stable chemistry, which may contribute to clearer water and protection for your spa’s plumbing, heating, and filtration systems.

• Natural, biodegradable composition with only sodium carbonate
• Chlorine-free and phosphate-free for gentler water
• Likely helps maintain a comfortable pH range and curb scale formation

How to use EcoOne pH Plus

• Test your spa water pH; if it’s below 7.4, dissolve 2 ounces in a small amount of water
• Pour the mixture into the spa and run the circulation system for several hours
• Retest and repeat until the pH sits between 7.4 and 7.8

• Store in a cool, dry place away from moisture
• Pair with EcoOne balance products for a complete care routine
